Abstract

1,015,154. Optical masers. WESTERN ELECTRIC CO. Inc. Oct. 4, 1962 [Oct. 16, 1961], No. 37498/62. Heading H3B. The resonant cavity of an optical maser is bounded by two parallel reflecting surfaces 21 and 24 between which is placed at least one partially transmitting reflector 22, 23 to divide the cavity into a number of gaps at least one of which contains a negative temperature material. The effect of the additional reflecting surfaces is to improve the made discrimination and it is stated that for optimum results the laser of Fig. 2 should have the reflectivity of the end mirrors 21 and 24 at least as great as that of mirrors 22 and 23. It is also stated that the length of the gaps which do not contain negative temperature material should be (2#v)<SP>-1</SP> where #v is the half width of the fluorescent emission line of the active medium.
